Django cannot access context variable in Jinja template
I am unable to access the context variable in the Jinja HTML template. The following is the code. view.py class Home(views.APIView): renderer_classes = [TemplateHTMLRenderer] def get(self,request): user, context = home(request) self.user = user return Response(context) def get_template_names(self): #code to return the correct HTML template return [template_name] The call "home(request)" in the "get" return a user object and dict. The following is the code def home(request): #user = get_user(name) #lines of code context={"form":form,'questions':get_questions(),'user_ques':user_questions,'dates':dates} Now, in the template I can access "questions" and dates variable. I cannot access the initial values of "form". The "form" is of type "forms.Form". When I debug, I can see the values are populated in the form variable, but when I check on the template side, they are "None". The same to "user_ques" is a dict of values, but on the template side its "{}". I am not sure what is happening. Any direction will help ! -

What is the proper syntax to call this Django view from another view?
I am trying to call the existing view below from a different view file in my Django project. I'm not fully understanding what the proper syntax would be to call this existing view to create a new folder. What would be the proper syntax to make a call to this view?

I tested using a simple python file and it works. My linux server is Ubuntu with python 2 as default. Any help and thought would be appreciated. -

Update a row in a Django data base based on a column value
I am new to Django and specifically Models and have been struggling to understand how to update data in the data base. Models.py: # Create your models here. class logTimes(models.Model): fast_finshed = models.BooleanField(default=False) start_date_time = models.DateTimeField('start fast') end_date_time = models.DateTimeField('end fast') In my View, I have a function to add a row of data when submitting one of two forms that will either add a new row of data or update an existing row of data.

Why does django-filter uses None value from choices defined for model field
Why does django-filter uses None value from choices defined for model field along with it's empty value label used for not filtering by certain field? Let's say, we have the following field in some model: FRUIT_CHOICES = [ (None, 'Choose one fruit'), ('AP', 'Apple'), ('BA', 'Banana'), ('KI', 'Kiwi'), ] SomeModel(models.Model): fruit = models.CharField(max_length=2, choices=FRUIT_CHOICES) And a filter defined for this model: class FruitFilter(django_filters.FilterSet): class Meta: model = SomeModel fields = ['fruit'] And this is the HTML we get: <select name="fruit" id="id_fruit"> <option value="" selected="">---------</option> <option value="">Choose one fruit</option> <option value="AP">Apple</option> <option value="BA">Banana</option> <option value="KI">Kiwi</option> </select> Basically, I can fix this by specifying choices for field in my filter form one more time but I feel like this would be dirty since I have a lot of choice fields in my model. I have been really struggling trying to fix this but it seems like either there is no information about this or I can't find right words to google it. Any help is greatly appreciated! -

PHP REST API Server send multiple data to client
I have PHP REST API Server. My client is written in python, client only sends request to my server and sometimes uploading file etc. My php script calling 9 functions. Each function changes string. I want to send this changed string to my client (python) after each function. Like in php file; $result = func1(); // it takes 5 seconds for example echo $result; $result = func2(); // it takes 5 seconds for example echo $result; ... But it only shows result when php script finished. I want to show it when each function returned data. I tried flush, ob_flush but it didn't work I think because of has not GUI (REST API). Maybe should I use django? Or better ways? I hope it was understandable, Thanks! -
Overloading and strategy pattern Python
I'm trying to write an email delivery system. I have this enum, for all users, users that were logged in the last 3 months and 6 months: class Receiver(enum.Enum): ALL = "ALL" THREE_MONTHS = "THREE_MONTHS" SIX_MONTHS = "SIX_MONTHS" The problem is, I'm trying to implement a Strategy pattern, so I need to enforce type checking. I know it is impossible by default, but ... any idea would be appreciated. I need it to look like: def send_to(Receiver.ALL): pass def send_to(Receiver.THREE_MONTHS): pass def send_to(Receiver.SIX_MONTHS): pass Yeah, I have Java background, so I'm trying to do method overloading here. And the general sender would pass the value accordingly: @api_view(["POST"]) def send_email(request): email_to = request.data["emailTo"] send_to(email_to) Note: I do not want to write multiple if checks or switch cases. It totally contradicts with Open Closed principle of Uncle Bob, since if there is gonna be additional case, then the method must be modified. Absolutely unacceptable. -
dockerized django build : how to run only once createsuperuser
I have a django docker container for the backend on my website. There is a volume for the database so i can save the database even if i change the backend configuration. I have tried to put the createsuperuser in my Dockerfile and in a script launched with "command" in docker-compose. But it seems the command is re-run each time the container starts or is rebuilt. I would like this command to be run only once, but i dont know how to proceed. The problem is the container is rebuilt in my ci/cd pipeline if i change the configuration files, and so the command is re-run in the Dockerfile in that case. I have seen this post Run command in Docker Container only on the first start but that also works only if the container is not rebuilt. A workaround with a createsuperuser command that would fail would work and that seemed to be the case with django previous versions (before version 4) but i now have "django.db.utils.IntegrityError: UNIQUE constraint failed: auth_user.username" error which tells me the command seems to be run multiple times and gives me errors in the database... -

How to add custom CSS for form labels to dynamically built Django forms?
I have a django form for which I need to increase the font size of the labels. Based on this StackOverflow discussion, what I need to do is add a CSS class and apply it to the control-label. How do I actually go about doing that? My form is populated like so: class MyForm(forms.Form): def __init__(self, *args, **kwargs): super(MyForm, self).__init__(*args, **kwargs) fields_to_add = { # many fields here, but all in this format. Removed for brevity. 'purchase_order_number': forms.ChoiceField( label="Purchase Order", choices=purchase_order_numbers), } self.fields.update(fields_to_add) self = add_classes(self) The add_classes code is as follows: def add_classes(self): """Add styling to form inputs.""" for key, value in self.fields.items(): self.fields[key].widget.attrs.update( {'class': 'form-control', # <- this is what I expect to change 'style': 'font-size: large',} ) return(self) I assume I need to modify add_classes to add some form of label-control or a custom class, but I don't really know how to actually make that change. -
Respuesta de Django se pierde y no llega la promesa al fetch

How can I get my html page to refresh upon completion of a django function?
I keep getting an error related to the csrf token when I try to employ consecutive submissions, and refreshing the page seems to work. The purpose of the program is to create zip files, so I figured the easiest solution would be to have the web page automatically reloaded once the zip file is done being created from the function in the views.py file and available for the user to open. The main issue I'm having is how to actually do that.
